Will My Car Run With These Upgrades Without Tune?

[Pugman1212]

I have a 86 mustang gt with built engine, aluminum heads, blower cam, Holley systemax 2 intake, 30lb injectors, 75mm pro m mass air. Vortec v1 5lbs of boost, stock processor no tune. I'm upgrading to 80mm pro m Nass air 80 mm throttle body, 42lb injectors, people are telling me car won't run good till its tuned... Runs fine now but needed to do some head work so I'm upgrading other things... Thanks

You were told correct. With those upgrades lets say it would be within you and your cars best interest to get a tune. You might get her running, maybe even decent where you think it's good, but damage will creep up fast.
